Research Abstract

A high-resolution laser-induced fluorescence (LIF) spectroscopy system has been developed using a tunable diode laser. Very high resolution of 10^<-7> has been achieved in determining the Doppler shift measurement. The minimum detectable velocity of the system is 2m/s, and the performance is maintained for more than 5 hours. The flow velocity field of neutrals in a plasma vortex is visualized and the role of neutral flow on the vortex formation in a plasma is clarified.
